As we all known, Soil nail components may also be used to stabilize retaining walls or existing fill slopes (embankments and levees); this is normally undertaken as a remedial measure.In order to better solve the engineering defects, we need a simple economic and fast reliable method of soil-nailing quality detection , providing reliable means for construction quality control.

Soil nail testing is performed to establish the bond stress within the stable zone of a slope. Typically, no more than 5% of the nails are selected for testing. Nails are incrementally loaded during testing.
As with all of Sinorock’s geotechnical services, our ability to provide value engineering and high-tech design and build capabilities, allows Sinorock to design and construct retaining walls with Soil Nails that provide truly cost-effective and aesthetically pleasing alternatives to more conventional shoring methods.

Built on over 5 years of geotechnical expertise, Sinorock’s soil nailing technology creates retaining walls that reinforce the soil mass without excavating the soil behind the wall. The soil nail walls are constructed in-situ and built in stages from the top down.

The advantages of Sinorock’s soil nailing technology can be applied to new permanent construction, temporary construction and to the restoration of existing structures. During the process, steel reinforcing elements (nails) are installed and grouted over a regular pattern to create a soil that acts as a coherent mass with improved shear strength. This newly reinforced soil mass can then provide stability for landslides, cut slopes and deep excavations.
